Unearth the Rich History and Spiritual Significance of the Maya at ATM Cave

The entrance of ATM Cave was first investigated by the Maya around 300–600 AD. However, it was during the period between 700–900 AD that significant ceremonial practices took place within its depths. For the Maya, caves such as ATM were deemed spiritual portals to Xibalba, the underworld, where essential rituals were performed to summon rain, ensure fertility, and gain favour from their deities. This deep-rooted connection to their cultural beliefs underscores the cave’s importance, both as a site for worship and as a repository of history.

The “Crystal Maiden”: This iconic skeleton, believed to be a young female, appears to shimmer due to the accumulation of mineral deposits over the years[11][21].
